Along with what Lee W. says, there are a couple things that can be done with 027 curve tracks to make the curves fit better. First you could use 027 half curves and half straights to open up the curve radius, second you could use a larger curve in 027 track size like a 42 inch curve in 027 profile. Or you could use Gargraves curves with 027 straight track, Gargraves smallest curve is closer to 32 inches than 31, so you have around five inch larger curve if you were to use Gargraves curves for the outside track(the one closest to the wall). All you need for gargraves to 027 track is the 027 adapter pins.
